Here they noted that the method of right and wrong cases was the most accurate of Fechner’s methods for studying the psychophysics of movement, but that it required a considerable number of trials and “is consequently not well suited for provisional, anthropometric, or clinical purposes” (p.447).

WebThis principle is used to model sensorimotor integration of proprioceptive and motor signals during arm movements (Chapter 3). The temporal propagation of errors in estimating the hand's state is captured by the model, providing support for the existence of an internal model in the CNS that simulates the dynamic behavior of the arm. WebPsychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or …
